Error: E315, keepjumps, scrolloff
" To Reproduce:
" Add this file to plugins; start Vim.
" Open file A (eg. 100) lines and B (eg. 200) lines
" Do G on both files
" When switching from B to A (longer to shorter) the message
" It's a bug ... should appear (in :messages)
"
" The error caught is E315 on the line 'let toppos=line('.')
"
" The (funny) solution is:
" let &scrolloff=&scrolloff
" (see the code below)
set scrolloff=3
function! ScrollOffBug()
echom "ScrollOffBug?"
" Solution:
" let &scrolloff=&scrolloff
try
let pos = line('.')
" error happens next:
keepjumps norm! H
let toppos = line('.')
catch /.*/
echom "It's a bug b=" . bufnr('%') . ", so=" . &scrolloff
endtry
endfunc
au BufEnter * call ScrollOffBug()
